Surface marker expression of undifferentiated hASCs cultured in BM (passage 1–2). The results are displayed as mean percentage of the surface marker expression of the four cell lineages used in the study.

surface protein	antigen	mean	s.d.	expression
CD14	serum lipopolysaccharide binding protein	2.7	1.2	negative
CD19	B lymphocyte-lineage differentiation antigen	1.1	0.3	negative
CD34	sialomucin-like adhesion molecule	19.7	2.0	moderate expression
CD45	leukocyte common antigen	2.9	0.9	negative
CD49d	integrin α2, VLA-4	62.3	18.2	positive
CD73	ecto-5′-nucleotidase	98.1	1.7	positive
CD90	Thy-1 (T cell surface glycoprotein)	97.6	2.5	positive
CD105	SH-2, endoglin	98.9	0.9	positive
CD106	VCAM-1 (vascular cell adhesion molecule)	1.2	0.7	negative
HLA-ABC	major histocompatibility class I antigens	73.9	18.4	positive
HLA-DR	major histocompatibility class II antigens	1	0.3	negative
